Use either route to get on the long avenue into Manzanillo Centro that runs along the railway yards and deep sea port. You will pass by the large expanse of shipping containers on the right and the bushes along the sidewalk shapped into animals, etc. Just as the container lot ends there are traffic lights. Take the right hand turn that goes over the railway tracks. Drive down the congested street to the end, but not onto the road that runs along the waterfront. Between the modern 2-3 story white building on the right and the strip of small shops, there is a small street that snakes around to a crossing gate. The man there will raise it for you. Drive though and park. The immigration building is on the left. Go in, take a number, and hope for the best.
